Dammit throttle body... are you serious?
Ok. So today I decided to finally clean my throttle body and IAC. After removing the TB and doing a total detailed cleaning, I went to change the gaskets. Well, seems like someone who previously had the car over torqued the coolant cover on the TB. 3 of the screws ended up snapping in half inside the coolant cover. Right now I have 4 of the screws removed and the other 3 sitting there. I figured this wouldn't be a huge deal since I would be able to pull the cover off still since it looks like it's not threaded. Well, that damn cover is acting like it's welded on there. I have it soaking in WD40 right now hoping it will penetrate and loosen.
Anyone have any good suggestions?
I'd rather remove this and replace the gasket than have to buy a new TB assembly.

I cant realy help, but nobody had to overtorque them. The screws become one with the casting. This is a common problem when steel screws are in alluminum threads. Happens all the time in throttlebodies. Thats why we have to use anti sieze on sparkplugs in alluminum heads.

Sympathy..your in a -----situation, I took mine apart a little while ago and was lucky enough to only snap 2 screws, the cover should come off it's not threaded but tight fit, once I got the cover off I was able to get one of the screws out because it didn't snap off flush so with the help of pb blaster and some small vice grips was able to work it out, but the other one broke flush and I had to drill and tap was lucky enough to get pretty straight on the broken screw and retap the hole
with m4x 0.7 metric tap if I remember right. then a trip to the hardware store and luckily they had metric replacement screws. Hope some of this might help. Maybe you'll be real lucky and they didn't snap flush. I forget what year yours is but if you get in a real bind I have a t.b off my 86 you can have, works fine just a little slop in the throttle rod. Good Luck.
Have a Happy new Year....Rich

Fortunately the 3 screws snapped flush only at the top of the cover about a 1/16th of the way in. I've actually already found my trust vice grips and will let patience carry me the rest of the way.
If I have issues, I may be in contact with you about the TB you have... I have an 85. Thanks a bunch!
And have a great new year!
